Indonesia was the first country to be seriously affected by the earthquake and tsunami created by the 2004 Indian Ocean earthquake on 26 December 2004, swamping the northern and western coastal areas of Sumatra, and the smaller outlying islands off Sumatra. Nearly all the casualties and damage took place within the province of Aceh. The time of arrival of the tsunami was between 15 and 30 minutes after the deadly earthquake. On 7 April 2005 the estimated number of missing was reduced by more than 50,000 giving a final total of 167,540 dead and missing.^[77]
